| decision making in controlling virus yellows of sugar beet in the uk. | virus yellows is an important disease affecting yield in sugar beet in the uk. myzus persicae (sulzer) is the most effective and efficient aphid vector of the three viruses causing the disease: beet yellows virus, beet mild yellowing virus and beet chlorosis virus. control of virus yellows disease is thus focused on the study and control of this aphid species. uk national surveys of virus yellows began in 1946 and these data helped to formulate disease forecasting schemes to optimise control. ov ... | 2004 | 15260306 |
| beet poleroviruses: close friends or distant relatives? | summary taxonomy: there are three members of the genus polerovirus (family luteoviridae) that induce yellowing of sugar beet: beet mild yellowing virus (bmyv), beet chlorosis virus (bchv) and beet western yellows virus-usa (bwyv-usa, fig. 1). non-beet-infecting isolates of bwyv found particularly within europe have now been re-named turnip yellows virus (tuyv). species-specific antibodies are unavailable, but the viruses can be distinguished by rt-pcr using primers specifically designed to the 5 ... | 2005 | 20565633 |
| divergence of host range and biological properties between natural isolate and full-length infectious cdna clone of the beet mild yellowing virus 2itb. | plant infection by poleroviruses is restricted to phloem tissues, preventing any classical leaf rub inoculation with viral rna or virions. efficient virus inoculation to plants is achieved by viruliferous aphids that acquire the virus by feeding on infected plants. the use of promoter-driven infectious cdna is an alternative means to infect plants and allows reverse genetic studies to be performed. using beet mild yellowing virus isolate 2itb (bmyv-2itb), we produced a full-length infectious cdn ... | 2014 | 23855287 |
